Cookie policy
Last updated: September 2026
In one sentence
We store the minimum needed for the page to work and to know where people get stuck. Advertising trackers (Meta and TikTok) are active so we know which ad brought you here, and you can change your mind here below whenever you want.
The necessary ones (always on)
Without these the page does not work properly. They are not used for advertising and they do not leave our domain.
acm_csrf— security cookie. It checks that the form was submitted from this page and not from a malicious site. It lasts 8 hours.brplus.sid— an anonymousidentifier for your visit, stored in the tab’s memory (sessionStorage, not a cookie). It lets us know that the same person saw section 3 and then filled out the form, without knowing who you are. It is deleted when you close the tab.acm.utm— stores which ad you came from, so we know which advertising works. Also in the tab’s memory.brplus.consentimiento— remembers this very decision you are making, so we do not ask you again on every visit.
Marketing (active, and you can turn it off)
These are third-party and they can follow you across other sites. They are active from the moment you arrive, and you can turn them off in one click below.
If you choose “only what’s necessary”, we stop sending them anything: not from your browser and not from our server. If the tracker had already loaded in this tab before you decided, the file stays in the browser’s memory until you reload, but it receives no event from you. It does not load again when you reload the page either.
- Meta pixel (Facebook and Instagram) — tells us which ad brought you here and lets us show you related advertising.
- TikTok pixel — the same, for our TikTok ads.
What we do NOT do
- We do not sell your data.
- We do not record what you type into the form before you submit it.
- We do not store your IP address.
- We do not use cookies for anything that is not on this list.
Change your decision
You can do it right here, right now, without digging through your browser settings:
Right now: you haven't decided, so the marketing ones are active. You can turn them off here.
You can also erase everything from your browser, in the privacy or site data section. If you delete brplus.consentimiento, we will ask you again on your next visit.
